Definitions

  • the invention relates to a filter bag with a flap and a spring element in the form of a preloaded tension spring which is mounted on the side of the flap on which it extends over the hinge and is loaded when opening the flap on train.
  • auxiliary devices for supporting the flap opening are known, the z. B. by means of a membrane over lever open the door.
  • the object of the invention is to provide a spring arrangement which allows a wide opening without large increase in force, so that the spring is not heavily loaded.
  • LSR Liquid Silicon Rubber
  • the contour of the spring element should be relatively flat so that it can easily be bent around the hinge of the flap.
  • a very flat and a degressive characteristic can be achieved, yet at the beginning by the effective lever arm, a high closure force can be generated.
  • the fulcrum the shutter is selected suitable and also a depression in the hinge is present, also a characteristic is possible, which goes into the negative region. This means that the closing force is less than 0 and thus the flap remains open.
  • the neutral (middle) fiber of the spring element must snap through in the region of the hinge on the other side of the axis of rotation.
  • a recess is mounted in the closure flap, in which the spring element completely immersed in the open state, so that no edge or elevation, which could hinder the flow, protrudes beyond the closure flap.
  • a seal can be attached to the spring element, which acts between the closure flap and the filter bag.
  • Fig. 1 shows a spring element 10 according to the invention, installed in a filter bag 12.
  • the flat spring element 10 is attached at its one end to the filter bag 12 and at its other end to a closure cap 14. Shown is an opening angle of the cap 14 of about 45 °.
  • Fig. 2 shows the built-in filter bag 12 spring element 10 in the state in which the flap 14 is closed.
  • Fig.1 and 2 shows Fig. 8 the prior art, in which a leaf spring 16 is used.
  • the leaf spring 16 has a crown (curvature in cross-section), so that the spring force decreases again after a certain opening angle. Shown here is an opening angle of the flap 14 of about 45 °.
  • the leaf spring 16 is effective as a bending spring. It is advantageous that the flow is not hindered in this embodiment by the leaf spring 16, since the air flows past on the other side of the closure flap 14.
  • the disadvantage is the heavy load on the leaf spring 16 upon wide opening of the closure flap 14.
  • Fig. 3 shows a schematic representation of the spring element 10 according to the invention, installed in the filter bag 12, wherein the flap 14 occupies the closed position. It can be seen that by a relation to the inner surface of the filter bag 12 and the closed flap 14 and its axis of rotation increased arrangement of at least one of the attachment points of the tension spring 10, the spring force with a lever arm with respect to the hinge axis acts as a torque that contributes to a safe closing of the Flap 14 leads.
  • Fig. 4 shows the spring element after Fig. 3 At this small opening angle, the spring element 10 is not yet on the hinge, but extends in the region of the hinge, regardless of any attachment to the attachment points and outside the area of the hinge, clear over it.
  • Fig. 5 shows the spring element 10 after 3 and 4 at an opening angle of the flap 14 of about 70 °. It can be seen that with this large opening angle, the spring element 10 bends about the hinge of the closure flap 14. A further opening of the closure flap 14 only leads to a very small increase in the torque and the spring load.
  • Fig. 6 shows one opposite Fig. 5 modified version at an opening angle of the flap 14 also about 70 °.
  • a recess in the hinge and in the flap 14 is present, in which the spring element 10 can dip. Depending on the size of this depression, it comes from a certain opening angle to a torque in the opening direction, so that the flap 14 remains open.
  • the neutral fiber of the spring element 10 lies below the axis of rotation of the hinge of the closure flap 14.
  • Fig. 7 shows possible characteristics of the spring element 10 according to the invention.
  • A denotes a curve which drops to a low level.
  • Another curve B drops to 0 and then rises again slightly. The point where the curves drop to zero or to the minimum can be determined simply by the geometry of the spring element attachment and the choice of spring.

Claims (9)

  1. Sac filtrant d'aspirateur comprenant un capuchon de fermeture et un élément de ressort (10) sous la forme d'un ressort de traction précontraint, disposé sur le côté du capuchon de fermeture (14) qui s'étend sur sa charnière et qui, lors de l'ouverture du capuchon de fermeture (14), est sollicité en traction,
    caractérisé en ce que
    les points de fixation de l'élément de ressort (10) sont disposés de telle sorte au niveau du capuchon de fermeture (14) et au niveau du sac filtrant (12) que celui-ci, jusqu'à un angle d'ouverture déterminé du capuchon de fermeture (14), s'étend librement sur la charnière et pour un angle d'ouverture plus grand, est courbé en appui contre une arête ou surface disposée sur ou à côté de l'axe de charnière.
  2. Sac filtrant d'aspirateur selon la revendication 1,
    caractérisé en ce que
    l'élément de ressort (10) possède une faible rigidité, de telle sorte qu'il peut être courbé avec un couple de rappel nettement plus petit, au niveau de la charnière du capuchon de fermeture (14), par rapport au couple de fermeture du capuchon de fermeture (14).
